Abstract
The surface lubricating process for latex product is especially suitable for 0.08-0.35 mm latex gloves, and features that: chlorinated solution with pH2-4 prepared from 30% hydrochloric acid 0.7-1.6%, bleaching powder 0.3-0.7%, and water, and silicone oil water solution 0.06-0.12%; the semi-finished latex product is soaked in the chlorination liquid for 6-20 min and then cleaned, and then treated by the lubricating liquid for 10-20 min, so that the treated latex product does not need powder lubrication, is comfortable and convenient to wear, and has no pollution in production and use.
Description
The invention belongs to the latex product process of surface treatment, particularly a kind of chlorination-lubricating process that is used for slim latex product surface lubrication processing.
At present latex product such as slim emgloves, its surface lubrication is to make releasing agent with talcum powder, treated starch is made separant, carry out again making after the sulfidizing its become glued membrane have certain intensity surface adhesion the emgloves of powdery lubricant.It is this that the powder emgloves is arranged is the external lubrication of doing the glued membrane surface with the powdery lubricant.Brought pollution for production environment and ecotope owing to used talcum powder and treated starch in the treatment process in a large number, the emgloves that has adhered to the powdery lubricant is simultaneously dressed uncomfortable, use inconvenient, that have even can cause skin adverse reaction, particularly in some specific occasions such as medical science, electronics, application is restricted.
The objective of the invention is to seek a kind of lubricating process that overcomes above-mentioned defective.
Chlorination-lubricating process of the present invention is, the demoulding is after the latex work in-process after the hot-water soak slaking, successively respectively in chlorated liquid of forming by hydrochloric acid, chlorinated lime, water and the lubricating fluid formed by the silicone oil aqueous solution after the soaking and stirring processing more routinely technology carry out sulfidizing, preferential combination of the present invention is: the chlorated liquid prescription is: (in weight proportion): 30% hydrochloric acid 0.7-1.6%, chlorinated lime 0.3-0.7%, all the other are water, and transfer to the pH value for 2-4; Its lubricating fluid prescription (in weight proportion) is: the 0.06-0.12% silicone oil aqueous solution; Priority processing operation of the present invention is: 1. the latex work in-process after the hot-water soak are soaked in the chlorated liquid, and the time is 6-20 minute; 2. the latex product of pulling out from chlorated liquid and cleaning with clear water soaked in lubricating fluid 10-20 minute.Certainly, the present invention also can adopt other proper ratio and suitable activity time.
Latex product after chlorination-swabbing of the present invention carries out the self-lubricating latex product that sulfidizing can make no powdery lubricant more routinely.
Technology of the present invention is specially adapted to the emgloves that film thickness is the 0.08-0.35 millimeter.The used silicone oil of lubricating fluid can be silicone emulsion, methyl-silicone oil or alkyl-silicone oil among the present invention.
Can clean with clear water through the latex product of chloridized among the present invention, the aqueous solution that also available hypo or other alkaline reagentss are mixed with is lubricated processing after cleaning with clear water after earlier it being washed till elutant pH and being 7 more again; In order to strengthen cleaning performance, can clean the cleaning of also can heating by normal temperature.
Further specify details characteristics of the present invention with embodiment below:
Wash 500 of the slim emgloves work in-process of the demoulding with water, wash after 50-60 minute with tap water flowing water flushing 15-20 minute with 600 kilograms of clear water bubbles more than 95 ℃, gloves after cleaning carry out chlorination-swabbing by the inventive method, processing sequence is as follows: 1. prepare chlorated liquid: 2 kilograms of chlorinated lime are made Eusol with elimination impurity after an amount of water dissolution earlier, this liquid adding is filled in the chloridized pond of 550 kg of water, reprocessing industry hydrochloric acid (HCl content is 30%) 4.8 kilograms, add the back sealing and stir half a minute, survey the pH value, and water to transfer to pH be 2-4, chlorated liquid; 2. prepare lubricating fluid: in 600 kilograms of clear water, add silicone emulsion 250-350 milliliter and promptly make lubricating fluid, stand-by; 3. 500 of the work in-process emgloves after cleaning are added in the above-mentioned chloridized pond, soaked 8-10 minute, after the time, feed clear water immediately, 600 kilograms of dirty water flushings of water yield 3-5 minute, logical again steam made water temperature rise to 45-50 ℃, washes 30-45 minute with flowing water after emgloves under this temperature soaks 15-20 minute, no chlorine flavor in the pond, the inside and outside surface adhering liquid of emgloves pH are till 7; 4. after the chlorination emgloves of cleaning is put into lubricating fluid, immersion was also stirred 20-25 minute.
After technology was vulcanized drying routinely again after emgloves after aforesaid method is handled was pulled out, get final product the self-lubricating emgloves of no powdery lubricant.
In above-mentioned through the gloves after the chloridized also can be earlier with 5% Sulfothiorine and (or) 20% sodium hydroxide solution cleans with clear water after neutralizing again, the raising that water temperature is suitable can be strengthened cleaning performance.
The inventive method is handled the modification of glued membrane surface molecular by chlorination-lubricated, the powder external lubrication that has that becomes latex product is no powder self-lubricating, improved the adhesive property of surperficial glued membrane, the powder-free rubber finger goods have been made, therefore no dust pollution in producing and using, the goods pellicle is smooth, color and luster is evenly bright, and preservation and use are all very convenient.Need not to use the powdery lubricant, dress convenient no skin irritation and untoward reaction, applied range.Be specially adapted to wide spectrums such as electronics, medical science.
Technology of the present invention is applicable to the surface lubrication processing of latex product, is particularly useful for the emgloves that thickness is the 0.08-0.35 millimeter.
